Summary: | The open-heart surgery of 26 cases has been performed in our hospital under extracorporeal circulation. Perfusate is diluted to 30% hematocrit during surgery. Lactated Ringer's solution is used as diluent because of improvement of intra-operative microcirculation. To reduce post-operative bleeding, we make an effort. The diluted blood in the machine was not infused femoral artery post-operatively, Instead of diluted blood, arm-to-arm blood (citrated fresh blood) is used soon after the operation. By transfusion of arm-to-arm blood, hematocrit of operated patient grow up to normal value rapidly. Then we can post-operatively prevent from anaemic hypoxia and secondary acidosis. On the other hand, arm-to-arm blood contains much thrombocytes than stored blood. This fact makes a contribution to decrease bleeding. Pot and base excess of femoral arterial blood suggest themselves adequate signs of total results of pulmonary function. With such efforts, we found less bleeding from operative wound. An average volume of post-operative bleeding is about 10cc/kg but a case. |
